Filed: 1975-01-30
Abstract: 1409901 Game apparatus F DE LESZCZYC-LASKOWSKI 30 Jan 1975 [28 April 1972] 19778/72 Heading A6H A box with a transparent lid in the form of a thin membrane, e.g. of plastics material, encloses a plurality of small paper rings which can be influenced to gyrate over, and then fall down upon, indicia such as numbers or letters on the bottom of the box, the movement of the rings being effected under the action of an electrostatic field induced in the membrane by the rubbing of the opaque lid of a second box within which the first box is enclosed. After induction the opaque lid is taken off so that the movement of the rings can be observed. The apparatus may be used as a number or letter selection device for football pools or other competitions.

Title: Improvements in or relating to dynamo-electric machines, more particularly arrangements for mechanically screening the windings thereof
Inventor: WESTON GEORGE EDWARD
IPC: H02K5/128
Filed: 1951-08-22
Abstract: 715,277. Machines with permanent magnets. SANGAMO WESTON, Ltd. Aug. 20, 1952 [Aug. 22, 1951], No. 19813/51. Class 35 The invention resides in the provision of a thin non-magnetic partition in permanent magnet generators, e.g. inductor or rotating magnet type. These generators are adapted for direct mounting on jet turbine engines as tachometer generators. Fig. 1 shows an inductor generator consisting of a disc 33 with upset rims 37, 38 respectively soldered &c. to the stator part 30 and to a cylindrical pole-piece 36 of the magnet 40. Thus this partition completely separates the rotating toothed inductor 42 from the stator windings 34. The stator in a die-cast non- magnetic casing 55 comprises the magnet 40, winding 34, magnet yoke 32 and the steel cylinder 30 having teeth 31 within which the toothed inductor disc 42 rotates. Fig. 4 shows a magneto with a rotating magnet 8 which is completely separated from the stator by a cup-shaped partition 5. The latter is closely fitted on to the four laminated salient poles 1. For magnet temperature compensation a temperaturecompensation ring 9 is fitted at one end of the magnet on the shaft 12. The Specification describes other methods of fixing the cup-shaped partition as e.g. in Fig. 5 (not shown), wherein the cup is cast about the stator pole-pieces. In all these disposition of the partition, the. stator winding is completely separated from the bearings. Besides partitioning the stator from the rotor system, the partition, which is of a high resistance'material with positive resistance-temperature coefficient, is used to compensate (because of its shortcircuit induced currents) for the output voltage drop due to the resistancetemperature coefficient of the generator windings. Specification 732,532, [Group XXXVI], is referred to.

Abstract: 765,115. Tailoring devices. MAGNI, C. July 6, 1954, No. 19820/54 Class 141. A device for use in tailoring garments comprises groups of shaped, flat, flexible and practically non-extensible elements which are adjustably connected, so that the device may be fitted and adjusted to the body of the proposed wearer, and then each group of elements may be spread out on a flat surface to give the profile for the tracing and cutting-out of the cloth. The device preferably comprises four groups, viz. right and left fronts, Fig. 1, and right and left backs (Fig. 2, not shown), the left groups being mirror images of the corresponding right groups. The differently shaped elements serve to determine width of back, side, and thorax, depth of sleeve curve, position of neck cutting, droop of shoulders, length of scapula, &c. The elements of each group are adjustably connected by slotted tongues or plates and winged screws, e.g. 4, 5. The groups of elements may be connected by plates, 14-16, and press-buttons, 22-28, or by hooks or straps. Soft, flexible elements, for, instance of foam rubber or felt, may be placed between the groups of elements and the wearer in parts where the garment is not to remain in contact with the body.

A process for casting ferrous-metal ingots comprises heating a slag to a temperature considerably above that at which it becomes liquid, rapidly pouring the heated slag into the mould so as to fill it substantially completely, and immediately thereafter casting the metal into the mould, the slag displaced from the mould being recovered. The slag, e.g. containing silica, alumina, lime, magnesia fluorspar, titanium oxide, alkali or alkaline earth metal compounds, borax, is substantially inert towards the metal to be cast and at the solidification temperature of said metal it has a low viscosity and a high interfacial-tension with regard to said metal, and examples of particular slag-compositions are quoted. Apparatus comprises ingot-moulds 7 supported on carriages 5 movable on a circular-track 3 from a position where the moulds may be filled with slag from a slag-melting furnace 1, to a position beneath a casting-ladle 10 on a gantry 11. Slag displaced by the cast metal flows into a slag ladle 13 via spouts 9, 14 and the ladle 13 may be moved on a runway to return the slag therein to the furnace 1. In a modification, the circular-track is replaced by two parallel-tracks, carriages being transferred from one track to the other in a continuous process.

In a zero-energy, graphite moderated, carbondioxide gas cooled nuclear reactor a central passage is provided for the reaction irradiation of test specimens. The passage is removable and may be replaced by one of different internal size. The specimen temperature is controlled by a flow of gas through the passage. The reactor core is formed of an outer annular drive region which operates at 60‹ F. and an inner test region, surrounding the central passage, the temperature of which is maintained at any required value by the movement through it of hot carbon dioxide. Gas flow also occurs at the separation of the core outer and inner regions and along the wall of the central passage. A thermal barrier of carbon black is mounted between the two core regions, and the central region is removable for fuel renewal. The central passage, a zirconium tube, is surrounded by graphite sleeves spaced apart by silica aerogel. Temperature controlled carbon dioxide gas flows through passages in the inner graphite sleeve.
